An update to GTViewer for iOSis now available. Version 3.0.33 contains a variety of fixes, but it also contains several major new features and enhancements to existing functionality. The list below highlights the most important items:

Most of the User-Defined Linestyle (UDLS) functionality in desktop GTViewer is now available in the iOS version. This includes embedded text and symbols on lines, complex dash patterns, and layered linear and text components. A few examples are shown below:

All Dash Pattern rendering has been improved to match the new dash pattern functionality in desktop GTViewer (including standard dash patterns and custom dash patterns defined in style definitions). On the desktop, the new dash patterns look slightly different (a shift from a Microstation style dash where all endcaps are vertical or horizontal to where all endcaps are oriented to the underlying line). GTViewer for iOS has always rendered endcaps that are oriented to the line, but the optimization used on the desktop are now used in the iOS version.

The Locate XY command will now support XY in the data's coordinate system as well as Latitude/Longitude coordinates (similar to desktop GTViewer's Locate XY).

Previous View has been enhanced to match desktop GTViewer's View History functionality which allows the user to step both forward and backward through the list of view locations and zoom levels.

URL Scheme (launching GTViewer for iOS from a URL) has been expanded to support Queries. The URL Scheme in GTViewer for iOS has always allowed other applications on the iPhone/iPad to launch GTViewer with a URL and locate on a specified coordinate. This new functionality will now support running a query to locate a feature using an existing query (like the command-line arguments on desktop GTViewer).

The Current Location, Previous View, and Raster toolbar icons now support a long press to display commonly used functionality above the toolbar buttons. You can now do a Long Press on the toolbar buttons instead of navigating through the menus.
